MANOA — Shearyna Labasan wanted to ensure that Maryknoll made a strong showing in its first state-tournament appearance since 2008.

The junior pitcher certainly did her part Tuesday night, tossing a complete-game no-hitter to lead the Spartans to a 6-0 win over Pearl City in a first-round game of the DataHouse/Hawaii High School Athletic Association Division I Softball State Championships at Rainbow Wahine Softball Stadium.

Labasan struck out 14 Chargers and allowed just three walks, relying on a steady defense behind her.

"It's a three-fold thing," Maryknoll coach John Uekawa said of Labasan's strong effort. "Of course, she does the throwing, but the coaches picked up a couple tendencies and corrected it and we went live with our catcher and she seems to getting a little more confident."

Uekawa said the development of Kasey Magadaro behind the plate has helped fuel Labasan's success.

"Shearyna's freshman and sophomore year, all she would throw is drops and that's how we got so many outs and she was getting away from those drop-balls," Uekawa said. "Now she's going back to them and look what we've got — so now we understand what is going on at a perfect time. It's just now we feel a lot more confident that we're going to get the ground balls, because our defense has been solid behind her and she has that trust in (Magadaro)."

Labasan got out of a few jams, stranding a runner in the second inning and got an inning-ending double play to negate back-to-back walks in the fifth. The Spartans then created some havoc on the bases in the bottom of the inning, when it sent nine batters to the plate and scored all six of its runs.

"That double play sparked our rally," Labasan said. "The defense did a tremendous job, they kept the ball in the infield and stopped everything."

Labasan said she was unaware that she had a no-hitter going until the seventh inning. Her teammates and coaches made sure she paid it no mind.

"I don't think they wanted me to think about it," Labasan said.

Uekawa said it was a strong outing by Labasan, but nothing new from his ace.

"The ILH is really tough and to be honest, she pitches like that every game," Uekawa said. "All season long, only Mid-Pacific scored six runs on, I don't think anybody else scored more than four, so this game was just a testament of how she can throw. We live and die with her arm."

Labasan and the Spartans advanced into Wednesday's quarterfinal round, where they will play Oahu Interscholastic Association champion and tournament No. 2-seed Mililani at 7 p.m.

Interestingly enough, Labasan's aunt is Trojans' head coach Rose Antonio.

"Her mom and my grandma are sisters," said Labasan, who won't change her approach for the game. "I'm going to try to not let it affect me and just play it like a normal game and come out hard against Mililani."
